Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7768, here are decompositions:
- 11 + 7757 = 7768
- 41 + 7727 = 7768
- 179 + 7589 = 7768
- 191 + 7577 = 7768
- 227 + 7541 = 7768
- 239 + 7529 = 7768
- 251 + 7517 = 7768
- 269 + 7499 = 7768
Showing the first eight; more decompositions exist.
